| 英文摘要 | Through intensive studies, we have established an index system for evaluating the loss and impact caused by large-scale flood disasters, and constructed a methodological system for pre-assessing the loss and impact caused by large-scale flood disasters. Through numerical simulation, submerged characteristics of large-scale flood can be determined. According to the characteristics of spatial corresponding distribution between land-use types and types of disaster-affecting subjects, we have realized spatialization for social and economic statistic data, and have completed spatialization evaluation on the loss and social impact caused by large-scale flood disasters using the spatial analytical function of GIS software. It is possible that large-scale flood can occur in the lower Yellow River. Flood management requires pre-assessment on the loss and impact caused by flood disasters. Nevertheless, there is no appropriate pre-assessment method for the lower Yellow River at present. By imitating the flood happened in Yuanyang, the north bank of the lower reach of Yellow River in 1958, we did pre-assessment on the loss and social impact caused by the overflow flood. We found that this method can be used to predict the types,. quantity and spatial distribution of economic loss caused by large-scale flood disasters. This method can determine population affected by disasters and degree and spatial distribution of disasters. Indirect loss can be predicted as well using this method. In general, this method can meet the needs of regions affected by flood for planning and making decisions in fighting floods and reducing loss. |
